Like ripples in a pond, electrons travel like waves through materials, and when they collide and interact, they can give rise to new and interesting patterns.
Bluefin tuna, a long-lived migratory species that accumulates mercury as it ages, can be used as a global barometer of the heavy metal and the risk posed to ocean life and human health, according to a study by Rutgers and other institutions.
Concept is now widely accepted after initial controversy around projects such as Yellowstone wolves – though opposition remainsScientists raise £15m to bring mammoth back from extinctionThe news that scientists are planning to bring back woolly mammoths to the Arctic tundra, by splicing DNA from Asian elephants with that of their extinct ancestors, has raised a few eyebrows in the world of...
The next generation of computing and information processing lies in the intriguing world of quantum mechanics. Quantum computers are expected to be capable of solving large, extremely complex problems that are beyond the capacity of today's most powerful supercomputers.
Reduced agricultural production, water scarcity, rising sea levels and other adverse effects of climate change could cause up to 216 million people to leave their homes and migrate within their own countries by 2050, the World Bank has warned.
Rutgers researchers have discovered some of the first molecular insights into how toxic proteins are regulated in neurodegenerative diseases such as Alzheimer's and Parkinson's.
New research tools are needed to fully develop quantum computers and advance the field. Now researchers have developed and tested a theoretical tool for analyzing large superconducting circuits. These circuits use superconducting quantum bits, the smallest units of a quantum computer, to store information. Circuit size is important since protection from detrimental noise tends to come at the cost...
Most of our cells are locked into place with the help of tiny anchors (called 'focal adhesions'). But if a cell morphs into a cancer cell, the chain can break, letting the cancer spread to other parts of the body. A team of scientists have now found the specific protein (or link) in the chain responsible for upholding the connection. The discovery gives scientists new directions for future cancer...
In a 'first of its kind' study, researchers found a potential direct connection between neurodegenerative diseases, such as Alzheimer's disease, amyotrophic lateral sclerosis (ALS), glaucoma, and the herpesvirus.
An approach to reducing greenhouse gas emissions that is informed by the ethical theory of utilitarianism would lead to better outcomes for human development, equity, and the climate, according to a new study.
A research team lays down the foundation for the expansion of supercritical fluid applications research.
A new study demonstrating the emergence of localized magnetism due to a 2D nanomaterial's unique, star-like atomic-scale structure has potential for applications in next-generation electronics based on organic nanomaterials, where tuning of electronic interactions can lead to a vast range of new electronic and magnetic phases.
A perspective article challenges the 'energy balance model,' which says weight gain occurs because individuals consume more energy than they expend. According to the authors, 'conceptualizing obesity as a disorder of energy balance restates a principle of physics without considering the biological mechanisms underlying weight gain.' The authors argue for the 'carbohydrate insulin model,' which...
In a study of more than 400 adults with normal blood pressure, those who had high levels of stress hormones detected in their urine were more likely to develop high blood pressure over the next 6-7 years. Higher levels of the stress hormone cortisol were also linked to an increased risk of cardiovascular events, including heart attack and stroke.
By using artificial intelligence to mine big data related to artists, film directors and scientists, researchers have found that years of exploration (studying diverse styles or topics) immediately followed by years of exploitation (focusing on a narrow area to develop deep expertise) can lead to a career's greatest hits.
A new study has shown that the protein RNF5 plays an unusual role in acute myeloid leukemia (AML). Unlike its expected role, marking aberrant proteins for destruction, RNF5 binds with a second cell protein called RBBP4 to control expression of genes implicated in AML. These findings have important implications for improving AML patient outcomes.
Transporting a single brick to Mars can cost more than a million British pounds -- making the future construction of a Martian colony seem prohibitively expensive. Scientists have now developed a way to potentially overcome this problem, by creating a concrete-like material made of extra-terrestrial dust along with the blood, sweat and tears of astronauts.
In times of exacerbating biodiversity loss, reliable data on species occurrence are essential. Environmental DNA (eDNA) - DNA released from organisms into the water - is increasingly used to detect fishes in biodiversity monitoring campaigns. However, eDNA turns out to be capable of providing much more than fish occurrence data, including information on other vertebrates. A study demonstrates how...
Researchers have now demonstrated a method by which specific cell types in human organs can be studied with micrometer precision. The method can be used to reveal previously unrecognized alterations in the pancreas, but it can also be used to study other human organs and diseases.
A new method designs nanomaterials with less than 10-nanometer precision. It could pave the way for faster, more energy-efficient electronics.
Men's sleep may be more powerfully influenced by the lunar cycle than women's, according to a new study.
A new study suggests textbook wording that portrays climate change information as uncertain can influence how middle and high school students feel about the information, even for students who say they already know about climate change and its human causes.
A new study has introduced a new surgical procedure to treat both children and adults with congenital intestinal malrotation, an inherited disorder that can cause the intestines to twist. The study also defines the disease presentation in both children and adults, identifies the patients at risk of intestinal loss, and assesses the long-term outcomes after different surgical interventions.
Usually, the individuals of a population of marine species that have the potential to disperse over long distances all share a similar genetic composition. Yet every now and then, at small, localized sites, small groups of genetically different individuals suddenly appear within populations for a short period of time. A new study explains how this chaotic formation of genetic islands can occur in...
Scientists explore the creation of artificial organelles. Artificial organelles generated from Exosome fusion can function as energy reserves in the damaged tissues.
A new, location-specific agricultural greenhouse gas emission study is the first to account for net carbon dioxide, methane and nitrous oxide emissions from all subsectors related to food production and consumption. The work could help identify the primary plant- and animal-based food sectors contributing to three major greenhouse gas emissions and allow policymakers to take action to reduce...
Engineers developed a way to grow tiny replicas of the pancreas, using either healthy or cancerous pancreatic cells. Their models could help researchers develop and test potential drugs for pancreatic cancer.
Findings suggest that a family's socio-economic status (SES) may influence children's composition of gut microbiome -- the mix of microscopic organisms within the digestive tract. SES includes economic resources such as education, income and occupation, and are reflected in living conditions, nutrition and psychosocial stress, according to the study, which focused on the education levels of...
An enormous amount of gravity from a cluster of distant galaxies causes space to curve so much that light from them is bent and emanated our way from numerous directions. This 'gravitational lensing' effect has allowed astronomers to observe the same exploding star in three different places in the heavens. They predict that a fourth image of the same explosion will appear in the sky by 2037. The...
